The "search hierarchy!" link will execute this search:
((122/101 <IN> CPC) <OR> (122/102 <IN> CPC) <OR> (122/103 <IN> CPC) <OR> (122/104 <IN> CPC) <OR> (122/105 <IN> CPC) <OR> (122/106 <IN> CPC) <OR> (122/107 <IN> CPC) <OR> (122/108 <IN> CPC))

This will show what classes derive from the input. Ex: entering 78/35 shows the derived classes and the search that can be used to find patents in those subclasses.
